Statistics is the science concerned with developing and studying methods for collecting, analyzing, interpreting, and presenting empirical data.

Statistics is a highly interdisciplinary field; research in statistics finds applicability in virtually all scientific fields and research questions in the various scientific fields motivate the development of new statistical methods and theory. In developing methods and studying the theory that underlies the methods statisticians draw on a variety of mathematical and computational tools.

UC Irvine's Department of Statistics was formed in 2002 and the Department is one of three departments in the Bren School of Information and Computer Sciences.
